P04Newborn affected by noxious substances transmitted via placenta or breast milk

P04 is the ICD-10-CM diagnosis code for newborn affected by noxious substances transmitted via placenta or breast milk. It belongs to block P00-P04 (newborn affected by maternal factors and by complications of pregnancy, labor, and delivery) and chapter 16 (certain conditions originating in the perinatal period). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P04.0 (delivery), P04.1 (medication), P04.2 (tobacco), P04.3 (alcohol), P04.4 (addiction), P04.5 (substances), P04.6 (substances), P04.8 (substances) and 1 more.

The conditions in its Excludes2 note aren't part of P04, but may be coded alongside it if the patient has both: congenital malformations (Q00-Q99), encounter for observation of newborn for suspected diseases and conditions ruled out (Z05.-), neonatal jaundice from excessive hemolysis due to drugs or toxins transmitted from mother (P58.4) and newborn in contact with and (suspected) exposures hazardous to health not transmitted via placenta or breast milk (Z77.-).

Code first: any current condition in newborn, if applicable.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised).
